HYDROCARBON-BURNEB.

Specification of Letters Patent.

Application filed April 3, 1913, Serial No. 758,679. Renewed Kay 14, 1914. Serial No. 838,468.

To all whom it may concern .Be it known that I, GILBERT PQNTBRiAND, a'citizen of the United States, residing at West Warren, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Hydrocarbon-Burners; and I dogdeclare the following to be a full, clear,-' and exact description ofthe invention, such as will .en-. able others skilled in the art to which it appertainsto make and use the same.

This invention relates to improvements in hydrocarbon burners and more particularly to the fuel feeding and mixing mechanism thereof.

One object of the invention is to'improve the fuel feeding and mixing mechanism shown in the United States Patent No. 1,012,821 granted to me October 29, 1912, whereby the same is rendered more efficient and reliable and may be more readily controlled. j

lVith this and other objects in view, the invention consists ofcertain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed, v In the accompanying drawings; Figure 1 is .a vertical sectional view of a' stove showing my improved burner and fuel feeding mechanism applied thereto; Fig. 2 is a horizontal sectional view of the same taken on the line 2-2 of Fig. 1'; Fig. 3 is a vertical cross sectional view of the burner taken on the line 3-3 of Fig. 2,; Fig. 4 is a detail vertical sectional view of one of the burner tips removed from the burner; Fig. 5 is a part side view and part longitudinal vertical section of a portion of my improved fuel feeding and mixing mechanism; Fig. 6 is a detail perspective view of the injector nozzle forming part of the fuel feeding and mixing mechanism and showing the parts thereof ,separated; Fig. .7 is a similar view of the nozzle looking toward the inner end thereof; Fig. 8 is a plan view of a modified form of burner having my improved feeding and mixing mechanism applied thereto; Fig. 9 is a longitudinalvertical sectional view of the burner and feed ing mechanism shown. in Fig. 8; Fig. 10 is a crosssectional view of the same; Fig. 11 is a plan view of another modified form of burner having my improved fuel feeding and mixing mechanism I applied thereto; Fig. 12 is a cross sectional view of the burner 'ment 5.

and feeding mechanism shown in-Fig. 11;

f Fig. 13 is a perspective view of another form of burner havingmy improved feedingand mixin mechamsmconnected therewith F ig. 14 1s a horizontal sectional view of still another-form of'burner showing a modified construction of the fuel feeding and mixing mechanism.

Referring more particularly to the first three figures of the drawings, ldenotes my improved burner which comprises a. hollow body having a bottom plate 2, sid'e and end flanges 3 and a top plate 4 spaced above the bottom plate to form a fuel compart- In the bottom plate 2 and top plate 4 are formed series of alined apertures 6 with which areengaged ventilating tubes all of which structure corres nds to the structure of the burner shown 1n the patent herein referred to.

Q In the top plate A: are formed series of burner openings 8 in which are arranged burner tips 9 in the form of threaded valve plugs constructed inupper and lower adjustable sections having fuel passages 10 and which are otherwise constructed and arranged. for operation as shown and described in'United States Patent No. 990,164 granted to me April 19, 1911, and a further description of which in the present instance is not thought to be necessary.

Oonnected 'with the body of the burner at one end isa fuelmixing chamber 11 which is connected at its outer end with a fuel sup ply chamber 12, to the outer end of which is connected a steam supply pipe 13. The chamber 12 is connected with the outer end of the mixing chamber or tube 11 by a union or other suitable coupling as "shown in Fi 5 of the drawin s and formed integral wit the inner end 0 the chamber 12 is a gas or oil injecting tube 14 in which is arranged a controlling valve, 15 and on the outer end of which is arranged a union or other form of coupling 16 by means of which a heating coil ma be connected with said injecting tube. gne end of the injecting tube 14 opens into the: chamber 12 near .the', inner end thereof and this end of the injecting tube is interiorly threaded to receive an in- 'ector nozzle 17 comprising a short tube which flares toward its outer end and has its inner end closed by a plate having therein a series of small perforations 18 through Figs. 2 and 3 of th supported in the outer end of the nozzle 17 is a spreaderordeflecting plate 19 which is formed. on the outer end'of a shank 20 the inner end of which has a threaded engagement with a centrally disposed threaded passage 21 in theinner; end plate of the nozzle. The deflecting plate or spreader is provided on its outer side with a screw driver slot 22 topermit the shank to be screwed inwardly or outwardly thus adjust ing the spreader22whereby the fluid is discharged from the nozzle in the form of a spray of. greater or less fineness. The 011 or gas when discharged into the tube or mixing'chamber 11 from the nozzle 17 mixes with the steam therein and is discharged therefrom, and into the body ofthe burner through perforations 11 in the tube 11.

Arranged in the lower side of the chamber 12 near ts. connection with th; steam supl i e13 is a drain ipe 23 aving a cutvgfl i al te 24 'as shown. The chamber 12 is also provided with a controlling valve which may be of any suitable construction. In the present instance the chamber 12 has arranged therein a partition 25 having therein a valve seat 26 with which is adapted to be engaged a steam controllin valve 27 whereby the passage of steamt rough the chamber 12 to the may be controlled.

The valve 27 is provided with a stem 28 which has a threaded engagement with a screw plug 29 arranged in a threaded aperture 30 in the lower side of the chamber 12 in line with the valve seat 26. The stem 28 of the valve passes through an prdinary stuffing box in the plug 29 whereby a fluid tight connection is ormed between the valve stem and the opening n the plug.

Connected with the injector tube 14 by the coupling or union 16 hereinbefore described is an oil heating and gas generating coil fuel mixing chamber 11 32 which is designed to occupy a position over the burner and which may be constructed in various shapes and designs to correspond with the construction and arrangement of the burner to which'the same is applied. In Figs. 1, 2 and 3 of the draw- 'ings the coil 32 is in the form of a plurality of loops arranged one within the other andof such size as to lie abovethe two outer-. most rows of burner tips whereby. the flame from these tips has a direct contact with the loops of the coil as clearly shown in e drawing. By thus arranging the coil 32 it will be seen that the oil will be effectually fast as the gas is consumed by the burner.

In order to generate sufiicient gas for starting the burner, I provide an auxiliary heating coil 33 the ends of which are connected to the oil supply pipe 34 to which the outer end of the coil '32 is connected.

are ventilating apertures 43 w heated and converted into gas after the burner is lighted and as The auxiliary heating coil 33 may be arranged at any suitable location in the oil supply.pipe 34 and in the inlet end of the .coil 33 is'arranged a cut-oft valve 35 while 33 after which the valve 36 in the oil pipe is closed and the valve 35 in the coil pipe is opened thus causing "the oil to flow through the coil '33 wherein the oil is primarily heated by the lamp or torch and suflicient gas thus generated to supply the burner until the main generating coil 32 has become heated to a suflicient extent for converting oil passing therethrough into gas. After the main coil 32 has thus been heated to a sufiicient extent the valve 35 in the auxiliary coil is closed and the valve 36 in the oil supply pipe opened, thus causing the 'oil to flow directly through the sup 1y pipe to themain generating coil as will be readily understood.

In Figs. 8, 9 and 10 of the drawings is shown a burner 37 having a slightly difierent arrangement of .burner tips from that shown 1n the first three figures of the drawg and in which the. main gas generating coil 38 is simplified. In this instance the coil 38 has but one loop but is otherwise the same as the coil 32 hereinbefore described.

In Figs. 11 and 12 is shown another slightly. modified form of burner 39 wherein the fuel receiving space shown in the first figures of the drawing is dispensed with and inthe bottom 40 of which is formed a .central fuel passage 41 and a series of laterally extending branch passages 42 which connect with the main passage and which have their outer ends turned upwardly and opening through the upper side of the bottom of the burner to provide fuel outlets which are threaded to receive the burner tips or valves as shown. Arranged through the bottom 40 of the burner between the outlet openings of the branch assages 42 v ich correspond to and are provided for the same purpose as the air or ventilating passages shown and described in the first form of the invention. The gas generating coil 44 for the burner 39 is constructed in the same manner as the gas generating coil 37 shown in Fig. 8 of the drawing. In Fig. 13 is shown another modified form of burner comprising a hollow head 45 to one side of which midway between its ends is connected the chamber 12 of the feeding and mixing mechanism. The head 45 forms a mixing chamber and has thereon series of nipples 46tto which are connected burner tubes 47 which are spaced apart and arranged in parallel relation as shown. In

the upper sides of the burner tubes 47 are formed series of gas discharging apertures in which are arranged my improved burner tips or valves 9 hereinbefore described. In this form of the burner there is also provided a heating and generating coil which is not shown in the present instance but which may be arranged over the burner tips in any suitablemanner and connected with the outer end of the injector tube as will be readily understood. I

In Fig. 14 of the drawings is shown another modified form of burner .48 which comprises a solid block of metal having therein a centrally disposed passage 49 which opens through one end of the block and has connected therewith at its outer end i atpoints between its ends outwardly projecting gas discharging passages 50 the ends of which curve upwardly and open through the upper side of the block in the same. manner as the branch passages 42 of the form of burner shown in Figs. Ill-and 12 and in which are arranged my improved burner tips 9. The block 48 has also formed therein a steam generating passage 51 which opens through and begins at one end of the block 48 and extends inwardly parallel to one side of the block as shown at 52, thence across theblock, beyondrthe inner end of the passage 49 as shown: at 53 and thence back through the opposite side of the bloclr as shown at 54 and has its inner end connected with or opening into the central pas-- sage 49 as shown at 55. It will thus be seen that the passage 51 passes entirely around through the block so that the fluid passing through this passage is heated and vaporized or turned to steam by the heated block when the burner is in use. In this form of the burner the passage 49 is designed to receive oil or gas which is supplied thereto through an oil or gas conducting pipe 56 which is connected with the outer end of the passage while the passage 51 is designed to receive water which is supplied thereto through a water conducting pipe 57 connected with the outer end of the passage. The water in passing through the passage 51 is vaporizedor turned to steam before being discharged into the oil or gas passage 49, said passage thus forming a mixing chamber in which the steam and oil or gas are mixed before'being discharged to the burner tips. In the burner 48 are also formed ventilating passages 58 which'correspond to and are provided for the same purpose as the ventilating passages shown and described in the other forms of the invention.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is:

, In a burner of the character described, a body having therein burner openings, a fuel mixing chamber connected with said body, a fuel supply chamber connected with said mixing chamber, a valved gas or oil injecting tube connected with said supply chamber, an injector nozzle arranged in said tube 1 and comprising a short tube having a flared discharge end and having its inner end closed and provided with perforations, said inner end having a threaded passage, a spreader arranged in the outer end of said nozzle and having a threaded stem engaged with the threaded aperture in the'inner end of the nozzle whereby the spreader is adjusted in the outer=end of the nozzle, a gas or oil supply pipe connected with said in.- jector tube, a steampipe connected with said fuel supply chamber, and a steam controlling valve arranged in said chamber.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- IIGSSQS.
